Walt Bellamy (born July 24, 1939 in New Bern, North Carolina) is a former pro basketball player. His half-brother is professional boxer Ron Bellamy.

Bellamy had a stellar 14 year career in the NBA and was the NBA first overall draft pick in 1962. He was the NBA Rookie of the Year in 1962, and his 31.6 point per game average that season is second all-time for a rookie to Wilt Chamberlain's 37.6. Bellamy also grabbed 19.0 rebounds per game that year - third best all-time for a rookie (to Chamberlain and Bill Russell). Due to trade scheduling skews during the 1968-69 season, Bellamy set the still-standing record for NBA games played in a single season with 88.

Bellamy is a prominent member of Alpha Phi Alpha, the first intercollegiate Greek-letter fraternity established for African Americans.

Bellamy was elected to the Naismith Memorial Basketball Hall of Fame in 1993.
